Let’s put this in perspective. Abraham Lincoln inspired generations in a speech that lasted two minutes. John F. Kennedy took 15 minutes to shoot for the moon. Martin Luther King Jr. articulated his dream of racial unity in 17 minutes. Steve Jobs gave one of the most famous college commencement speeches of our time at Stanford University in 15 minutes. If you can’t sell your idea or your dream in 10 to 15 minutes, keep editing until you can.
Ideas don’t sell themselves. Be selective about the words you use. If they don’t advance the story, remove them. Condense, simplify, and speak as briefly as possible. Have the courage to speak in grade-school language. Far from weakening your argument, these tips will elevate your ideas, making it more likely you’ll be heard.
